Please help us. Our daughter has cerebellar hemorrhage. What can we do to learn more about it?

Cerebellum. Go to a library or medical library and look this up in a neurology or neurosurgery text, or the merck manual.
Lots. 1st , if she is your dependent child, talk to your doctor. Google has tons of information but it can sometimes be overwhelming. And of course, you can ask more specific questions right here. A bleed can be relatively minor or quite serious depending on cause and how much bleeding.
